Phosphorus is an essential nutrient for all life on earth and has a major impact plant growth crop yield. The forms of phosphorus that can be directly absorbed utilized by plants are mainly HPO42- H2PO4-, which known as usable phosphorus. At present, the total content soils worldwide 400-1000 mg/kg, only 1.00-2.50% plant-available, seriously affects development agriculture, resulting in high level scarcity available Traditional methods applying fertilizer cannot address deficiency problems; they harm environment ore material nonrenewable natural resource. Therefore, it imperative to find alternative environmentally compatible economically viable strategies scarcity. Phosphorus-solubilizing bacteria (PSB) convert insoluble soil into plants, thus improving uptake utilization plants. However, there no clear systematic report mechanism action PSB. this paper summarizes discovery process, species, distribution PSB, focusing physiological mechanisms outlining processes acidolysis, enzymolysis, chelation complexation reactions related genes regulating PSB acidolysis enzymatic well phosphate transport molecular direction its pathway examined. effects structure abundance microbial communities also described, illustrating how interact with microorganisms indirectly increase amount soil. And three perspectives considered further exploring utilizing synergistic multi-omics approach, PSB-related regulatory different levels investigating application fungicide. This aims provide theoretical support providing optimal management elemental future.

Here, a degraded soil, located in semi-arid Mediterranean region, was characterized 17 years after organic amendment with sludge or compost (differing their stabilization degree) for restoration purposes. To do this, (i) soil physicochemical properties and plant cover, (ii) matter (SOM) content composition, (iii) basal respiration enzymatic activities, (iv) abundance, taxonomic functionality (shotgun metagenomics) of microbial communities were studied. Increased SOM nutrient contents found from amended plots respect to the control, no differences between types. This is explained by lasting effects amendments higher cover. Thermal pyrolytic analyses showed that process enriched mainly intermediate recalcitrance high chemical diversity. composition did not differ abundances activities plots, without sludge. Shotgun metagenomics changed functional terms unamended but these rather limited. The treatments driven increasing Actinobacteria decreasing Proteobacteria plots. Soil some adaptation increased predominant nutrients forms. This, together detected, conspicuous reported effectiveness studied confirmed here an integrative perspective.

Fertilization and cultivation management promotes soil phosphorus availability by enhancing soil P-cycling enzymes and the phosphatase encoding genes in bulk and rhizosphere soil of a maize crop in sloping cropland

Fertilization and cultivation managements exert significant effects on crop growth soil-associated nutrients in croplands. However, there is a lack of knowledge regarding how these practices affect soil phosphorus-cycling enzymes functional genes involved regulating global P-cycling, especially under intense agricultural management sloping A long-term field (15-year) trial was conducted 15° based five treatments: no fertilizer amendments + downslope (CK); mixed treatment mineral organic manure (T1); alone (T2); 1.5-fold (T3); contour (T4). Bulk rhizosphere samples were collected after the maize harvested to determine P fraction, P-cycling enzymes, phosphatase-encoding genes. Results indicated that fertilization significantly increased inorganic (Pi) (Po) fractions compared CK, except for NaOH-extractable Po T1 T3 bulk soils, respectively. For treatments, content Pi pools larger than T4 soils. lower vice versa NaHCO3-P HCl-Po rhizosphere. We also found activity acid phosphatase (ACP), alkaline (ALP), phytase, phosphodiesterases (PDE), phoC phoD gene abundance with effect ALP encoding gene, Soil carbon (SOC) microbial biomass C (MBC MBP) main predictors phoC- abundance. strong association fraction cycle mainly mediated by microbial-related processes. Together, our results demonstrated an adequate amount or combined plus more effective promoting availability enhancing ALP, This provides valuable information sustaining microbial-regulated similar lands worldwide.
